Added a flag in dummy_request() to inform middleware that the request is a dummy.

Browse Source 
This is useful for middleware that perform destructive changes in
process_response(). They rightfully expect process_response() to only get called
once per thread, but it happens twice during a Page preview when running under
Django 1.10's middleware system. This flag lets the middleware know that they
should potentially skip their destructive operations.
